Abstract
Due to the role of the brain’s neuromodulatory system, biological organisms have the capacity of responding to the ever-changing environment rapidly. This work presents that the mechanism of the neuromodulatory systems through a developmental network can provide a control framework for the artificial agent to regulate its behavior. With the dopamine, serotonin, acetylcholine and norepinephrine modulation, the agent can operate autonomously, effectively carry out specific functions, e.g., to pursue a friend and avoid the enemy, and make suitable and instant decision when the environment changes. Goal-directed pursuing behavior in two simulation scenarios demonstrate the effect of the proposed neural modulatory systems, such as attentional effort, reinforcement learning and addressing the unexpected uncertainty.
